Answer:
-9x-2y-24
Step-by-step explanation:
-x-24-8x-2y
To combine like terms, the only ones you can combine would be the -x and -8x (due to both have the exponent of 'x')
-x= -1x, so -x-8x = -9x
-9x-2y-24 would be your answer since nothing else has like terms.
Simplify the equation to find X:
7/8 (-32 - 48x) +36 = 2/3( - 33x - 18) - 10x
Distribute the terms in parentheses:
-28 - 42x + 36 = -22x - 12 - 10x
Collect like terms
-42x + 8 = -32x - 12
Add 32x to both sides, and subtract 8 from both sides:
-10x = - 20
Divide both sides by -10
x = 2

Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
I cant see the triangles but look for 1 with a 90 degree angle. if it has 1 90 degree angle then that is you answer
